After digging up a list from eighteen years ago, people around Su Yu began to die mysteriously.
A colleague with a broken leg, a witness silenced, an eunuch who died in a back alley...
Everyone warned him: Stop investigating the cause of the late emperor's death.
Until he saw the mother who was supposed to have been dead for eighteen years - she was imprisoned in the palace, holding the last piece of evidence in her hand.
That night in the Qianqing Palace, the emperor looked at the people who came to seek revenge and laughed at them for hitting the stone with an egg.
But he didn't expect that the arrow that shot through his heart came from his biological son.
On the day when the new emperor ascended the throne, Su Yu stood under the plum tree and thought to himself: All this is far from over.
But he didn't notice that the new emperor's eyes were falling on him.
